One Officer Dead, Several Shot By Gunman At LA Airport

Police officers stand near an unidentified weapon in Terminal 3 of the Los Angeles International Airport on Friday. Officials said a gunman who opened fire in the terminal was wounded in a shootout with police and taken into custody.

A lone gunman walked into one of the nation's busiest airports Friday in Los Angeles and opened fire with an assault rifle, killing at least one transportation security officer and wounding another, police and TSA officials say.

Authorities have identified the shooting suspect as Paul Anthony Ciancia, 23, originally of New Jersey. Officials did not immediately provide a motive for the assault.

The attack left at least seven people needing medical treatment (including the shooter), officials said, and forced the evacuation of a terminal and delays of flights coming into and out of the airport. At least one of the injured is listed in critical condition, a hospital official said.

The gunman, officials said, was taken into custody after exchanging fire with airport police. LAX Police Chief Patrick Gannon said the assailant "pulled an assault rifle out of a bag and opened fire in the terminal."

LA Mayor Eric Garcetti said that the situation could have been much worse, reports NPR's Newcast.

"The fact that these officers were able to neutralize the threat as they did," Garcetti said. "There were more than 100 more rounds that could have literally killed everybody in that terminal."

NPR's Kirk Siegler spoke with Stacy McLennan, who was waiting in line at the Air Canada check-in counter when the shots rang out.

"I was at ticketing and one of the TSA agents turned around and said so and so had been shot and we turned around and it was a really young kid, TSA agent, and he had blood coming out of his abdomen and there was blood coming out from his hand," McLennan said. "We all were just standing there and didn't know what to do, and the next thing we knew, they said 'run, run,' and so we all just took off running."

Update at 5:10 p.m. ET. Witness: 'We Just Hit The Deck':

Xavier Savant, who witnessed the shooting, tells The Associated Press that he was waiting in a security line when he heard a "bam, bam, bam" burst of gunfire. He and others "just hit the deck. Everybody in the line hit the floor and shots just continued," Savant said.

He said the shots subsided and people bolted through past the scanners and made their way to the tarmac.

This statement from a TSA official:"Earlier this morning, a shooting occurred at Terminal 3 at Los Angeles International Airport. Multiple Transportation Security Officers (TSOs) were shot, one fatally. Additional details will be addressed by the FBI and local law enforcement who are investigating the shooting."

Separately, NPR has been told by the LA Coroner's Office that a 40-year-old male is dead, but no further information was available.

A spokesman for the American Federation of Government Employees, the union that represents TSA workers, says: "We have received first-hand confirmation from a reliable source that the shooter was not a TSO."

Meanwhile, UCLA Medical Center Director Dr. Lynne McCullough told reporters that the hospital is treating three adult male patients from the airport shooting — one is in critical condition; two are listed as fair.

Gannon said the gunman moved around the terminal, including into the security checkpoint area, before he was "engaged in gunfire" by airport police who were able "to successfully take him into custody."

"We have multiple victims that have been shot and have been transported" to hospitals, along with the gunman, Gannon said.

A fire department official followed Gannon to the microphones and said seven people have been treated for injuries (presumably including the shooter), with six taken to hospitals.

-- "When gunfire broke out there was a stampede people, all of us hiding under seats we didn't fit under, we burst through the door to outside."

Update at 1:11 p.m. ET. 'Situation Has Ended':

NBC Los Angeles says it is being told by officials that "the situation has ended." But, obviously, that doesn't mean things are back to normal at the airport. The FAA says planes are being held on the ground after landing.
